HEATING DEVICE.

To all whom. it may concern Be it known that I, WILLIAM F. SHAUGH-messy, a citizen of the United States, and a resident of New York,borough of Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Heating Devices, ofwhich the following is a specification.

My invention relates to heating systems and has for its primary objectto provide a construction characterized by superior simplicity andefiiciency and having a capacity for perfect regulation within limitsthat can be adjusted at will to meet the requirements of every possiblerange of conditions that may arise in practice.

A further object of my invention is to provide a heating device in whichthe heat is stored and radiated by one medium and supplied by another;the latter medium or agent being preferably non-combustible in itsnature and being supplied to the heating device in such a way that itsadmission thereto is controlled by the thermal condition of the firstmedium; the expansion of the radiating medium serving to restrict theadmission of the heating agent until the latter is shut olf entirely.

Still another object of my invention is to provide the heating devicewith manually operable means whereby the point at which the expansion ofthe radiating medium acts to shut off the heating agent can be adjustedto suit convenience or necessity; whereby perfect regulation within anydesired limits can be obtained.

A preferred embodiment of my invention is illustrated on theaccompanying drawings, wherein the same characters of reference areemployed to indicate the same parts throughout the several views.

On said drawings Figure 1 is a side elevation of a heating device orradiator with a regulator attached in accordance with my invention; Fig.9. is a longitudinal section of a detail of my construction; and Fig. 3is a similar view of one form of regulator which I employ in thepractice of my in vention.

Referring particularly to the drawings, I utilize a radiator 1,supported by feet 2, this radiator being hollow to receive a suitableheat-radiating medium such as water. Within the radiator 1 andpreferably at the bottom of the same I locate a hollow body or cylinderat, to which the agent which im- Specification of Letters Patent.

parts heat to the water is supplied. The admission of this agent to theinterior of the body 4 is regulated by suitable automatic mechanismshown at 5, this mechanism comprising a casing communicating with thecasing formed by the radiator 1 and having therein a piston 6 connectedby a rod 7 to a valve 8. This valve is located in a pipe or conduit 3,which will be an ordinary steampipe when steam is used. A suitablecasing 9 may be employed to house the valve 8, and this casing will beconnected to the pipe 3 on the one side and the cylinder t on the other,as will be readily perceived.

The radiator may be constructed of any number of sections 10, having airspaces 11 for circulation of the air in the room or apartment containingthe radiator, and thus give a greater heating eifect. The water may besupplied thereto from a pipe 12, which may be connected to a suitablewater source; the pipe 12 being united by a branch 13 to a T 15, fromwhich a section 16 leads directly into the radiator. A valve or cook 14:may be inserted in the branch 13, to turn on the water and shut it offat will. Likewise a suitable drainpipe 17 having a valve 18 will beprovided. As shown on Fig. 1 the water will enter the casing of theradiator at the top and be drawn off at the bottom, and this arrangementpermits of the flushing out of the radiator, so that the same can easilybe cleaned without taking it apart or dismantling it. The pipe 12 may berun into every room of the building, and a common branch may be used tounite the pipes 18 to conduct the drain water to the sewer. The casing 5is connected to the T 15 by a short section of piping 19, so as to allowthe water in the radiator to enter the casing 5, as will be fullydescribed later.

The section 19 may be joined to the casing 5 by any suitable coupling. Ihave shown on the drawings a bushing 20, having a flange 21. This flangeis engaged by a hollow threaded nut 22, which screws upon a threadedboss 23 of the casing 5. The bushing is internally threaded and thelower end of the section screws into the same.

In the casing 5 I locate the piston 6 above mentioned, this piston beingcup-shaped and inverted, and being surrounded by a suitable packing. Therim 24: of the piston is turned outward, and to the piston is secured aring 25, between which and the rim the packing 26 is held. The pistonrod 7 is secured to the piston preferably by nuts 27, and a suitablespring or other yielding body 28 may be placed between the spring andthe bottom of the casing to prevent the too easy movement of the piston6.

I prefer to make the rod 7 in two sections, the lower being hollow andreceiving the upper in screw-threaded engagement, so that the totaloperative length of the rod can be increased or diminished to suit thedegree of regulation aimed at. The lower of the rod sections will have acollar 32 thereon, and the upper will be received in a sleeve havingscrew-threaded engagement with a boss 29 in the bottom of the casing 5.This sleeve 30 will have a handwheel 31 thereon to facilitate turningthe same, and it will engage the collar From this it will be perceivedthat by turning the sleeve to move it toward the casing 9 the valve 8can be closed entirely, or the extent to which the spring 28 may openthe valve altered at will.

The lower section of the rod 7 enters the valve case through a gland orstuffing box 33, and the casing 9 unites with the steampipe by means ofa threaded boss 34 and unites by means of a similar boss 35 with asection 37 leading into the body 4. A suitable nut or packing 36 may beused to make a tight joint bet-ween the boss 35 and the section 37. Thisnut or packing may also be used to unite the casing 9 and pipe 3. Itwill be internally threaded to receive either the boss 3st or 35, andthe adjacent threaded end of pipe 3 or section 37. Obviously anyconvenient form of joint for these parts of my construction may beemployed, and suitable washers inserted to make the same proof againstleakage.

In order to secure the body or cylinder a in place inside the radiator 1I mount the cylinder in a special form of nut which not only serves as asupport for the cylinder but also acts at the same time as a cap orclosure member for the aperture in the radiator 1 through which thecylinder is admitted. This nut is shown at 38, and it is provided on oneside, the inner side, as will appear from inspection of Fig. 2, with anannular rib 39, that is threaded both inside and out. Into this rib thecylinder is screwed, having its end 40 threaded for this purpose. Theother end of the cylinder is closed, and the cylinder and cap form aclosed chamber for receiving the steam or other agent adapted to impartheat to the water or other radiating medium in the radiator 1. Thethreads on the outside of the rib 39 enable the nut to be screwed intothe opening in the radiator through which the cylinder is inserted, andwhen screwed home the cap completely closes this opening. The cap orclosure member'38 also has a threaded opening to receive the pipe 37,shown at &l; and is further provided with a threaded port 42 to receivea tube 43, the function of which will be presently set forth. This port42 leads to a passage a l in the body of the cap 38 which runs to avalve Q5 secured to the cap in a threaded opening 4:6. This valve servesas a vent or blow-off for the cylinder at, and may be of well knowntype. It is sufiicient to say here that the vent valve &5 is soconstructed that it will allow air to escape from the cylinder f as soonas the steam is turned on and enters the cylinder, but as soon as thesteam reaches the valve d5, the same will close automatically andorevent the escape of the heating agent. N ien the steam is turned off,and the chamber cools again, the vent valve will open and allow air toenter the cylinder to relieve the vacuum caused by the condensationtherein.

It will be observed from Fig. 2 that I place the opening 41 in the cap38 so that it will communicate with the lowest part of the cylinder at,and locate the opening 42 so that it will communicate with the highestpart of the cylinder. I thus facilitate the draining of the water ofcondensation back into the steam line where it is taken care of by thetraps, and at the same time I am enabled to put the tube 43 so highabove the lowest part of the cylinder 4:, that should there be any waterby any mischance in the cylinder 4 when the steam is turned on, thelevel thereof will never reach the tube. Hence none of it will be blownout through the vent valve 45 and all spitting and sputtering at thisvalve, with the consequent soiling of adjacent objects will be entirelyeliminated. I consider this an important advantage, and the nut 38 is aquite important detail of my construction.

From the above description the operation of my heating device will bereadily understood. lVater is admitted to the radiator to fill the same,and the level of the liquid therein can be read by means of an ordinarygage 011 the radiator 1 near the top. The radiator 1 will be filled, andI may provide a vent for the air which may afterward be closed. Ofcourse all the air need not be exhausted, since some space may berequired to allow the water to expand to a certain degree before itactually moves the pis ton 6. Some of the water entering the radiatormay be allowed to flow directly into the regulator casing, but I mayclose this casing by means of a valve in the pipe 19 at this time ifdesired. After the radiator is filled the steam can be turned on andwhen the water has expanded to the re quired point it will act on thepiston 6, and restrict the further admission of thesteam to the cylinder4. Finally it will close the steam line altogether, and the entrance ofthe steam will cease till the temperature of the water falls and thevolume contracts, thus allowing the spring to act and the piston tolift. By turning the wheel 31, the amount or extent to which the valve 8is allowed to open, can be varied. I can in this way regulate theadmission of steam to the cylinder so accurately that the radiation willbe too rapid to allow the water to expand at all; or at least too rapidto permit the water to expand sutliciently to shuto'lf the steamaltogether. This allows separate regulation for every individualapartment of the building in which the heating device is used; and itenables the occupant to get as much or as little heat as he desires orneeds according to his surroundings. It provides in fact for regulationto suit every possible range of conditions that are likely to be metwith in every day life. Another advantage of my invention resides in thefact that the casing 5 will prevent bursting of the radiator if theradiator 1 should ever freeze over night, after steam is turned off bythe anitor. In such an event the water on congealing will simply fillthe regulator casing, and damage will be avoided. The owner thereforeneed have no fear of accident at any time.

it will be seen therefore that my heating device is as simple as it ispossible to make it; the construction of the same is easy and cheap; andany degree of regulation that is wanted can be had by the user simply manipulating the parts which determine the extent to which the steam lineis to be allowed to open. The radiator casing can be flushed out at anytime and replenished, and no skilled attendant is ever needed. Anyhousekeeper can understand the structure and operation of it and evenneglect and ill usage cannot result in any serious trouble.

Having described my invention, what I claim as new and desire to secureand protect by Letters Patent of the United States is 1. in a heatingdevice, the combination of a body forming a cap or closure and having arib or flange on one side thereof, a hollow body having one end receivedby the cap and surrounded by the rib, said cap being adapted to supportthe hollow body in horizontal position projecting from the side of thecap, the hollow body having its outer end closed and forming with thecap a closed chamber, the cap having a passage leading to the inside ofthe hollow body adjacent to the lowest part of the same and adapted todrain said hollow body and having a second passage leading to the insideof the hollow body adjacent the highest part thereof, and a tubereceived by the inner end of the second passage and extending into thehollow body in close proximity to the top of the same, whereby when thetube operates as a vent tube, water collecting on the bottom of thehollow body will not be expelled therethrough.

2. In a heating device, the combination of a casing for receiving amedium adapted to store and radiate heat, a hollow body in the casinghaving its outer surface in contact with the medium, means for supplyingto the inside of the body a noncombustible agent adapted to impart heatto the medium, said agent being kept out of direct contact with themedium by the walls of the body, a valve for controlling the admissionof the agent to the body, a casing communicating with the first casingand having a piston therein, a rod connecting the valve and pisston,whereby the expansion of the medium will move the valve and finallyclose the same, resilient means in the piston casing opposing the actionof said medium, said rod having a collar thereon, and a screwthrcadedsleeve carried by the piston casing and engaging the collar, said sleevehaving a hand-wheel thereon, whereby the opening of the valve may belimited, or the valve closed independently of the expansion of themedium.

3. In a heating device, the combination of a casing for receiving amedium adapted to store and radiate heat, a hollow body in the casinghaving its outside surface in contact with the medium, means forsupplying to the body an agent adapted to impart heat to the medium,said agent and medium being kept out of direct contact by the walls ofthe body, a valve having a rod comprising two adjustable sections forcontrolling the admission of the agent to the body, a casingcommunicating with the first casing and having a piston therein, saidrod entering the said casing and being secured to the piston, wherebythe expansion of the medium will move the valve and finally close thesame, a yielding member opposing the action of the medium, said rodhaving a collar thereon, and a screw-tln'caded sleeve carried by thesecond casing and engaging the collar, said sleeve having a handwheelthere on, whereby the opening of the valve may be limited or the valveclosed independently of the expansion of the medium.
